Be it known that I, EMILE DAVID CAHEN, acitizen of the Republicof France, and domioiled at 7 Avenue Niel, Paris, in the French Republic, have invented a certain new and useful Safety Steering Mechanism for Automobile Carriages, of which the following is a. full, clear, and exact description, and for which application for patent has been iiled in ro France on the 18th of March, 1905.

' This invention relates to a safety steering mechanism for automobiles. This mechanism is characterized by the spindle of the steering-wheel controlling the pivots of the i 5 steering road-wheels by two distinct sets of connections in such a way that the breakage of one of these parts does not ai'l'ect thc safety of the steering device.

The invention is described, with reference zo to the accompanying drawings, in which- Figure 1 is a diagram in side elevation, and Fig. 2 is a plan view of the saine. F ig` 3 is a plan of a modification.

The steering-pillar A is provided with two 2 5 worms B and C, with which respectively engage two toothed sectors I3 and C. The two worms B C may, however, be united to form a single one. The sector B is fast to a spindle b, suitably journaled, and to this spindle is fixed an arm b', jointed at b2 to one end of a connecting-rod b3, joined at its other end to the lever-arm d, which is fast to the pivot of one ofthe steering road-wheels D. The other y toothed sector C is fast to a spindle or rod c, 3 5 suitably journaled, and this rod carries a lever-arm c', jointed at c2 to one end of a conlever-arm d' of the pivot of the second steering road-wheel D.

40 The two steering roadfwheels D D are connected together either, as shown in Fig. 2, by two rods E, attached to the arms CZ d', which are fast to the pivots, or, as in Fig. 3, by a sin- Speccation of Letters Patent.

vSAFETY STEERING NIECHANISIVI FOR AUTOMOBILE CARRlAGES.

Patented March 6, 1906.

vone of the rods b3 c3 which breaks, the steering'is maintained by the other of these rods and the rod In the case of the pattern having two rods E the steering is maintained even if one of the rods b3 c3 and one of the rods E should be broken at the same time. L

In any one of these arrangements I may interpose at any suitable position among the connections cushioning devices made of springs or otherwise, as is commonly done in single steering mechanisms.

The invention is not restricted to the arrangement illustrated and may be modified. Thus, for instance, the steering-pillar may be fitted with screws and nuts instead of worms and segments, as in the construction illustrated.

Having thus described my invention, what I claim as such, and desire to secure by Letters Patent, is

A safety steering mechanism for automobiles, in which the pillar of the steering-wheel controls two sectors ornuts connected respectively by two sets of connecting-rods and ivots of the two steering road-wheels, the atter being also connected together by one or two sets of levers and coupling-rods.

In testimony whereof I have signed my name' to this specification in the presence of two subscribing witnesses.
